摘要：

An event accompanied by two single hyperfragments emitted from a Xi(-) nuclear capture at rest was found in a nuclear emulsion. It is interpreted as a Xi(-)-C-12 bound system decaying into either a)(Lambda)H-4 + Be-9(Lambda), b) H-4(Lambda) + Be-9(Lambda)* or c) H-4(Lambda)* + Be-9(Lambda). The binding energy of the Xi-C-12 system is obtained as a/) 3.70(-0.19)+(0.18) MeV, b) 0.62(-0.19)(+0.1)8 MeV and c) 2.66(-0.19)(+0.18) MeV, respectively. The system is considered as a Xi- hypernucleus in the cases a) and c). In case b), this event and another event of the same type (Yokohama event) can both be interpreted as a decay from the Xi-C-12 system in 2P state when a shallow Xi(-)-nulcear potential is assumed.
